Y Locatedalongscraper-wheel they are whipped upwardly by the blades 20, as seen in Fig. VII, thereby causing the leaves to be carried upwardly between the scraper-wheel and the revolving face-plate 12 with their unstripped sides facing the blades 20. The blades 20 are then permitted to act upon the unstripped sides of the leaves to remove the outer covering therefrom. At this time the main portions of the leaves have been freed from their outer coverings and the ber alone remains except at the butt-end of each leaf. The continued travel of the chain 11 conveys the leaves upwardly around the periphery of the face-plate 12 past a traveling carding and combing baud 25, that is provided with aseries of prongs 26, by which the fiber is carded. The carding and combing band 25 travels on pulleys 27 and 28 and a driven pulley to be hereinafter mentioned. When the chain 11 has passed under the face-plate 12, its utility as a carrier for the leaves ceases, and it passes over an idler 29 and downwardly to and under an idler 30, that is adjustably mounted in hangers 31 by means of adjustment-screws 32, the said chain passing then back to the drum 6.

As the leaves A emerge from the under edge of the revolving face-plate 12 and pass upwardly beyond said face-plate their butts are caught by a transfer-rope 33, that is arranged to travel in a groove contained by the revolving face-plate and on a series of idlers 34 and the idler 29, the leaves being,r thereby conveyed by said transfer-rope across the space voccupied by the idler 29.

The idler 29 receives a series of endless carrier-cables 35, that pass upwardly from an idler 36, carried bya shaft 37, that is adjustably mounted in hangers 38, the said shaft being held by adjustment-screws 39. The course of the cables 35 is downwardly from the idler` 29, over which they pass, and under a second revolving face-plate 40, thence upwardly over a discharge-wheel 41, and again downwardly to and beneath the idler 36. The second revolving face-plate 40 is similar in form to the revolving face-plate 12. Oset from the revolving face-plate 40 is a revolving scraper-wheel 42, similar to the scraperwheel 19 and similarly positioned with relation to the revolving face-plate 40. As the partially-cleaned leaves are conveyed bythe transfer-rope 33 onto the cables 35 by the chain 11, the cleaned fiber ends of said leaves pass with said cables downwardly between the cables and the periphery of the revolving face-plate 40, and as the butts of the leaves pass over the idler 29 they are freed from restraint. The iberof the leaves is then caught by the cables 35 and conducted under the revolving face-plate 40, and the butts there enter at the point 43, (see Fig. VIL) between a stationary face-plate 44 (similar to that 24) and the scraper-wheel 42. As the butts of the leaves pass between the revolving scraperwheel 42 and the stationary face-plate 44 and one side of each butt is acted upon by scraperblades 20', carried by the scraper-wheel 42 to remove the outer covering from the fiber in the butts of the leaves, and as the movement of the parts continues, the butts of the leaves are whipped upwardly by the scraper-blades as the leaves pass the aXis of the scraperwheel, thereby causing the opposite sides of the butts of the leaves to be acted upon as the butts are carried between the scraperwheel 42 and revolving face-plate 40 in similar manner to that described in connection with the scraper wheel 19 and revolving face-plate 12. The butt-s of the leaves are thereby thoroughly stripped of their outer covering, and as they emerge from their passage between said face-plate and scraperwheel the ber passes directly over the delivery-wheel 41 to be discharged from the machine, falling downwardly from said deliverywheel and onto a discharge -rope 45, that travels on the delivery wheel 41 and on sheaves 46. The discharge-rope 45 conveys the ber from the face-plate 40 over the delivery-Wheel 41 and discharges it from the machine, as illustrated in Fig. VII.

We will now describe the driving mechanism of the machine.

47 designates the main driving pulley, mounted on the shaft 21, that carries the scraper-wheel 19, as stated. On the same shaft 2l is a pulley 48, that is connected by a belt 49 to a pulley 50, mounted on the shaft 2, that carries the second scraper-wheel 42. On the shaft 21 is also a pulley 51, that receives a belt 52, through which power is transmitted from the shaft 2l to a driven pulley 52 on a shaft 53. On the shaft 53 is a pinion 54, that meshes with a spur-wheel 55, carried by a shaft 56, that is geared by a pinion 57 to a spur-wheel 58, fixed to the shaft of the second revolving face-plate 40 and by which said face-plate is revolved. Power from the shaft 56 to drive the first revolving face-plate 12 is transmitted through a sprocket-wheel 59, carried by said shaft 56, that is connected by an endless chain 60 to the sprocket-wheel 18 on the shaft 17. The pinion 16, carried by the shaft 17, meshes with the spur-wheel 15 and imparts movement thereto to effect the rotation of a revolving face-plate12. The crushing-wheel 8 is driven by power applied tc the sprocket-wheel 10 of the shaft of said wheel, around which an endless chain 10 passes, and thence to a sprocketwheel 61, carried by a shaft 62, that has driving connection with thespur-wheel15 through pinions 62a and 17. Power to drive the carding and combing band 25 is obtained through the pulley 63, mounted on the shaft 42, that receives a belt 64, which passes upwardly and over a pulley 65 on a shaft 66, that also carries a pulley 67. The pulley 67 receives the hackling-band, which passes therefrom to the pulleys 27 and 28. One of the sheaves 46, on which the delivery-rope 45 travels, is driven ICO IIC

by a belt 69, (see Figs. I, III, and V,) that is applied to a pulley 56a on the shaft 56 and a pulley on the shaft that carries said sheave 46.'

In order to provide for the lateral adjustment of the revolving face-plates 12 and 40, we employ set-screws 70, that bear against the ends of the shafts of said plates (see Figs. III and IV) and through means of which the shafts may be moved longitudinally to the proper degree, as desired, and to provide for the adjustment of the shafts 2l and 42a by which the revolving scraper-wheels are carried we utilize set-screws 7l, by which the said shaftsV may be shifted longitudinally to accommodate any desired lateral adjustment of the scraper-wheels. Y In Figs. IX and X We have shown a modication wherein the leaves may be carried directly across the entire machine, being held throughout their entire course by the butts, this construction providing for the stripping of the main portion of the leaves only, leaving the butts unstripped. In this form of construction 6a designates the main crushing and feed wheel, and 1liL the carrier-chain. The carrier-chain 1la passes entirely across the machine, first downwardly under the revolving face-plate l2, then over the idler 29 and under the second revolving face-plate d and over the delivery-wheel 4l, and downwardly beneath idlers to return to the starting-point. The fibers are conveyed from the revolving face-plate 12a to the face-plate 40a byatransfer-rope thatpasses overtheidler 29a. 19 designates the first scraper-wheel, and 42h the second scraper-wheel.

We claim as our invention- 1. In a machine of the class described, the

combination of a revolving face-plate, a revolving scraper-wheel having blades on the Y' side face thereof opposing said face-plate, and

means for conducting the leaves to be acted upon to said scraper-wheel and face-plate, substantially as described.

In a machine of the class described, the combination of a pair of crushing-wheels, a revolving face-plate, a revolving scraper- Wheel having blades on the side face thereof opposing said face-plate, and means for conducting the leaves to be acted upon to and between said scraper-wheel and said faceplate, substantially as described.
